| Abstract(in English) | Synchronous optical code-division multiple access (CDMA) using modified prime sequence codes (MPSCs) with an adequate interference canceller is suitable to realize a reliable multi-channel visible light communication (VLC) system. In this paper, we propose a new dimming control scheme for multi-channel VLC. The scheme assigns codewords of an MPSC or an inverted MPSC to each user. The average brightness is determined by the ratio of users to whom the inverted MPSC codewords are assigned. We investigate the flickering time period, variance of light intensity, and bit error rate of the proposed scheme. |
